Description

Guide strip for a running track of an escalator or moving walk

description

The present invention relates to a running rail for an escalator or moving walk.

Escalators and moving walks are known from the prior art, which have a supporting structure. In the structure run rails are arranged between a first deflection region and between a second deflection region.

EP 1 679 280 A1, for example, shows a running track with a complex profile, which can be fastened on a support. The running rail is formed in one piece and has a previously formed web with a leading edge, which the rollers of a step band of an escalator or the roles of a

Pallet band of a moving sideways leads.

EP 2 050 708 A2 also shows a running track for escalators and or moving walks. Also, this track has a complex profile, which has appropriate paragraphs to guide the rollers of a step band of an escalator or the rollers of a pallet band of a moving sideways.

The production of such rails with integrated guide edge is complicated and expensive. Due to the production, the design has certain limits. In addition, integrally formed guide flanks have a radius in the transition to the running surface of the running rail, on which running surfaces the rollers run in the direction of movement. This radius can severely damage the edge of the rollers or wear over the masses.

It is an object of the invention to overcome the disadvantages of the prior art. In particular, a running rail for an escalator or moving walk is to be made available, which is inexpensive to manufacture and allows gentle guidance of rollers. This object is achieved by the devices defined in the independent claims. Further embodiments emerge from the dependent claims.

An escalator with a step band or a moving walk with a

Pallet strip has a first deflection region and a second deflection region, wherein the pallet strip or the step band between the first

Deflection region and the second deflection region is arranged circumferentially. Furthermore, the escalator or moving walk includes at least one, between the

Guide rails arranged to guide the step belt or

Pallet band. The running rail has at least one base surface with a running surface for rollers of the step belt or pallet belt. Furthermore, the

Escalator or moving walkway at least one guide rail with a guide flank for laterally guiding these rollers, wherein the rollers when driving in lateral contact with the guide edge. The guide rail is a separate component and during installation, the position of the guide rail is thereby selected relative to the running rail.

With track in the present document all immovable parts of the escalator or the moving walk are called, which support the rollers of the tread band or pallet band between the two deflection against gravity and roll on the running surfaces of the rollers or parts, which rollers on the lifting of the treads prevent. This can thus be more rails, raceways, Gegenführungsschienen and the like. The rollers are, for example, rollers or chain rollers of a step belt or a

Pallet band. The fact that the guide rail is formed as a separate component, this can be easily finished, assemble and adjust.

The pallet belt or step belt usually includes a plurality of pallets or steps, which are arranged between two roller chains. The rollers of the roller chains support on the rails and usually run smoothly straight ahead. With increasing mileage, the chain links, chain pins and the bearing bushes in the roller chains are worn and it can deviate

Extensions come between the left roller chain and the right roller chain. These minimal differences are sufficient that the arranged between the roller chains pallets are no longer arranged completely orthogonal to the direction of movement and thus a side run occurs. This sideways or skew results in a lateral force which causes the rollers to deviate from their theoretical direction of motion. Since the rollers only come into contact with the guide rail when this side run occurs, it is important that the rollers come into direct contact with the leading edge of the guide rail when guided. This direct contact makes it easy for a service person to hear but also feel that the rollers touch and are guided by the guide flank. The service person can then carry out targeted maintenance work.

Due to the separation of running rail and guide bar can for the

Guide bar manufacturing process can be selected, which differs from the

Distinguish manufacturing process of the remaining track. In addition, embodiments can be formed, which can not be realized or only very expensive in a one-piece manufacturing process. In particular, such guide rails have no radius in the transition region between the tread and

Leading edge on. It is even conceivable that the guide rails are designed such that the guide edge does not reach all the way to the base surface, but at least in the region of the guide flank there is a spacing between guide flank and base surface or running surface. Furthermore, there are no restrictions on the choice of material for the guide rails. Preferably, such

Guide rails made of any of the following materials or alloys: steel, steel alloys, aluminum, aluminum alloys, brass, bronze,

Bronze alloys, polymer materials, glass fiber reinforced polymer materials and the like. Particularly advantageous is the use of polymer materials for the production of the guide rails, if their hardness is less than the hardness of the rollers, so that in a contact wear of the guide rail and not the role occurs. The advantage is that the guide rails can be exchanged much easier than the rollers.

For special applications, however, higher requirements may mean that the material of the guide strip must be harder than the material of the roll. Such special applications can be extra long escalators and moving walks For example, in subway stations, in airport buildings or in the for

Maintenance personnel are arranged difficult to access installation conditions.

On the running rail, a guide bar may be arranged in sections.

For example, it is conceivable that in the direction of movement of a guide bar, the rollers drive a short distance unmoved on the track. Only after a certain distance follows, for example, another guide bar. It goes without saying that with such a sectional arrangement of guide strips a further cost saving compared to a, known from EP 1 679 280 AI

Running track with molded, continuous guide edge results. By such a sectional arrangement of the wear of the side edge of the rollers can also be substantially reduced.

The guide bar can be arranged on the base next to the actual running surface of the rollers or the running rail. For example, a detachable connection or arrangement is conceivable. The direct mounting of the guide rail on the base of the track is made possible to reduce the height of the track. There are no production-related minimum heights specified. By a detachable arrangement of the guide bar, the guide bar is easy to replace in case of excessive wear or damage.

The running rail can have at least one further base surface with a running surface which is arranged below the first base surface, wherein the arranged on the first base tread for a run of the rollers of the step belt or pallet band and the other tread for a return of the rollers

Step band or pallet band are provided. By using a separate component as a guide rail, it is possible that the running rail is configured for example as a simple U-profile or C-profile.

For example, is located on the upper leg of the C-profile, the tread for the forward while on the lower leg of the C-profile, the tread for the return is located. One or more guide rails can be arranged both on the base for the flow and on the surface for the return. The guide rails for the forward movement of the rollers can be arranged offset in the direction of movement to the guide rails of the return. By an offset arrangement of the guide rails, the track is loaded less with lateral forces, resulting from not quite orthogonal to the direction of movement, running stages or pallets.

The running rail and / or the guide bar may have fastening means which are designed such that a lateral adjustment of a position of the

Guide bar transverse to the direction of movement of the rollers is possible. Thus, for example, the useful life of the guide bar is extended. For example, if the leading edge is worn, the guide bar can be laterally adjusted or adjusted to prevent excessive play between the

To allow guide rails and the rollers of a step or pallet. In addition, it allows easier initial installation of the track. The side play can be adjusted during installation on site and thus depending on the system.

The running rail may have one or more guide rails in the flow and / or in the return. Thus, despite sections guide a smooth running of the escalator or the moving walk can be ensured because a lateral deflection of the step belt or pallet band can be intercepted and corrected early.

At least one guide strip may have a sensor for measuring or detecting side forces acting on the guide strip. Such a sensor may be, for example, a strain gauge measuring bridge (DMS) or a switch. Of course, other configurations of sensors such as

Radar sensors, optical sensors of all kinds, ultrasonic sensors, GSM antenna modules used as sensors and the like more conceivable. The use of sensors allows, for example, that in case of excessive stress of the

Guide bar issued a warning and / or the system is shut down. The sensor can be used to detect impacting rollers or to measure side forces, a temperature, a speed or to measure

Be configured vibrations and vibrations. Of course, other measuring systems or sensors are conceivable, which can accommodate different operating conditions. At least one guide strip configured with a sensor can be displaced laterally relative to the other guide strips in the direction of the running surface of the rollers, that is to say that they are arranged protruding toward the remaining guide rails in the direction of the rollers. Such a guide bar is then primarily not only the lateral guidance or the lateral guidance of the rollers but should measure the acting lateral force early. This guide rail with sensor can thus be used as an early warning system for lateral positioning of the step belt in the escalator or the pallet band in the moving walk.

A flank angle between the guide flank and the tread may be between 90 ° and 140 °, preferably between 90 ° and 135 °, more preferably between 90 ° and 125 °.

An inventive guide rail for a running rail serves as previously described, for lateral guidance of rollers, in particular of rollers of a step belt or pallet belt. The guide strip has a guide flank with a flank angle and is designed as a separate component from the guide rail. Due to the separate training is made possible that the guide rail and / or a running rail can be particularly easily manufactured and assembled.

The guide rail is essentially an elongated component extending in the direction of movement of the step belt or pallet belt. For example, the guide rail may be a parallel to the running rail arranged rod with trapezoidal, rectangular, square or round cross-section. Of course, other embodiments are conceivable, for example, made of profiled bars or profile tubes guide rails.

The guide rail may have attachment means for attachment to a track rail. Preferably, the fastening means are designed such that the guide strip can be adjusted in its lateral alignment transversely to a direction of movement of the leading roles. For example, this is a slot opening formed orthogonally to the theoretical direction of movement, through which the guide rail on a running rail or by means of a screw can be attached to one of the track associated fastening means.

The guide flank can have in at least one end region of the guide strip in the direction of movement a convex curvature and / or an entry angle between 1 ° and 45 °, preferably between 5 ° and 35 °, particularly preferably between 10 ° and 25 °. An entry angle is understood to be an angle between an ideal direction of movement of the rollers (theoretical direction of movement) and a straight line in the leading edge in the end area in the plane of the base area.

Such a curved or kinked end portion allows easy catching or pointing and aligning of roles, if they deviate by side run from their optimal career. Preferably, both end regions of the guide flank are provided with such convex curvatures or inlet angles, so that the rollers can be instructed and aligned independently of the direction of movement forwards or backwards. However, it is also conceivable that the guide rail has only such an end region. For example, the guide rails can also be completely straight, but arranged at an angle corresponding to the entry angle to the direction of movement. Thus, although only the operation of an escalator or a moving walk in one direction is possible, the

Guide rails are accordingly easy to produce.

A sensor, for example a strain gauge measuring bridge, a radar sensor, a GSM antenna serving as a sensor or a switch or push button for detecting impact forces or lateral forces acting on the guide flank can be arranged on the guide strip. By virtue of the fact that the guide rail is equipped with a sensor, it is possible, for example, to react to excessively high lateral forces by generating and transmitting an error message. However, the sensor may also be configured to sense other variables of operation, such as the temperature of the rollers, their speed, vibration and vibration, and the like.

The sensor may be arranged in a region between two attachment means. It goes without saying that the sensor is preferably arranged on the side facing away from the guide edge of the guide rail. Another aspect of the present invention is the use of a track as described above and / or a guide bar as previously described for guiding rollers, wherein a guide bar is equipped with a sensor. A measured by the sensor size, such as a force or a distance measure, is used to generate maintenance messages. For example, such a variable or such a value can be picked up by a signal processing unit and further processed. It is conceivable that automatically status or

Maintenance messages are sent or the operation is stopped. Possible maintenance messages include:

• with low measured lateral force: a control of the system and possibly the implementation of minor adjustments or maintenance work by the service personnel is necessary within two weeks,

• at a medium lateral force: a control of the plant by the

Service personnel with adjustment of the chain tension or replacement of the roller chain is necessary within 24 hours and only limited driving possible,

• with high measured lateral force: the operation of the system is stopped

For safety reasons interrupted until a check or maintenance by the service personnel.

The values "low", "medium", "high" are usually given values, sizes and mass, which are not limited to the side force, and similar status or maintenance messages are also available when certain conditions are met

Operating temperatures, operating speeds or the occurrence of predetermined vibration values conceivable.

As previously mentioned, the guide strip may have at least one sensor for detecting or measuring at least one measured variable. This measure can be the structure-borne noise of the step belt or pallet band, vibrations, the bandage thickness of rollers, the thickness of the dirt adhering to the track and / or the rollers or the position of a ball bearing ring of a roller relative to its roller axis. On the basis of figures, which represent only embodiments, the invention will be explained in more detail below. Show it:

Execution analogous to the section AA shown in Figure 5. Figure 1 shows a schematic representation in side view of an escalator 10, which is arranged on a supporting structure 11 and which connects a lower level El with an upper level E2. The supporting structure 11 is exemplified in the style of an old bridge to clearly show that this supporting structure 11 of the

Freedom of design of the architect can be left. Of course, the supporting structure 11 may also be a concrete stairway, a truss or two I-beams. The supporting structure 11 must meet certain rigidity and load bearing requirements that the manufacturer of the escalator or moving walkway dictates to the architect.

On this building to be created, supporting structure 11 shots 12 are provided or to be attached later, on which the parts of the escalator 10 are mounted. For better clarity, only three receptacles 12 are provided with reference numerals, although in the present example, a receptacle 12 is provided for each support structure. The receptacles 12 may be simple mounting plates, the

For example, with a reinforcement of the supporting structure are directly connected.

Of course, other suitable receptacles 12 such as concrete anchors,

Threaded rods, welding plates, screw holes and the like more usable.

The escalator 10 comprises a first deflection region 13 and a second deflection region 13

Deflection region 14 and between the deflection regions 13, 14 arranged

Support structures 15, rails 16, balustrades 17 and a circumferential step band 18. For the sake of clarity, only one support structure 15 is provided with a reference numeral. The step band 18 is deflected in the upper level E2 and in the lower level El and thus has a Stufenband- flow 19 and a step band return 20. For the sake of clarity, the detailed description of the step band 18 has been omitted.

From the figure 1 it is clear that the rails 16 are divided into rail sections 21, 22, 23 and bolted together by means of connecting plates 25. The track sections 21, 22, 23 preferably have an equal length, but they can, as can be seen in FIG. 1, also have different lengths. The rails 16 are supported by a plurality of support structures 15 on the supporting structure 11. Of the support structures 15 are only those against the viewing plane directed supports 26 visible, therefore, the support structures 15 will be explained in more detail below in the description of Figure 3. Although support structures of the moving walk shown in FIG. 2 are described there, the construction and the function of the

Support structures 15 of the escalator 10, however, correspond to the support structures shown and described in FIG. Each of the supports 26 has a foot attachment portion which is rigidly connected to the associated seat 12 of the support structure 11 as shown.

FIG. 2 shows, in a side view, a schematic representation of a moving walkway 50 which is arranged on a supporting structure 51. As a supporting structure 51 is a floor or concrete foundation, which has sufficient strength.

Of course, the moving walk 50 can also be mounted on one of the supporting structures, as mentioned in the description of Figure 1. Also, the floor has receptacles 52, to which the components of the moving walk 50 are attached. These components include a first deflection region 53 and a second deflection region 54 and support structures 55 arranged between the deflection regions 53, 54.

Running rails 56, balustrades 57 and a circulating pallet band 58. Thus, the structure of the moving walkway 50 substantially corresponds to the structure of the escalator 10 described in Figure 1, even if in the present embodiments of Figures 1 and 2 at the escalator 10, two rails 26 one above the other are shown arranged and the moving walk 50 only a running rail 56th

Also, the rails 56 of the moving walkway 50 shown in Figure 2 are in

Rail sections 61, 62, 63 and 63 are supported by the support structures 55, the Fußbefestigungsbereiche are secured to the receptacles 52. If the individual raceway sections 61, 62, 63 and their associated support structures 55 are already assembled in the factory to roadway modules, the transport from the manufacturer to the installation site and the assembly of the moving walkway 50 or the escalator 10 on the prepared at the installation, supporting structure 11, 51 are significantly simplified.

FIG. 3 shows, in a three-dimensional view, a roadway module 70 of the moving walkway 50 from FIG. 2, formed from three support structures 55 and two running rails 56A, 56B or running rail sections arranged opposite one another. On Only a small portion of the pallet band 58, namely a pallet band portion 59 of the pallet band leader and a pallet band portion 60 of the pallet band recoil, are shown on the rails 56A, 56B to show the function of the rails 56A, 56B. The individual pallets 64 of the pallet band 58 are also shown only halfway to show the two roller chains 65A, 65B and their rollers 74 on both sides of the pallet band 58. The support structures 55 each have two supports 66A, 66B, which are rigidly connected to one another by a transverse strut 67.

The rails 56A, 56B are formed as C-profiles. In this case, the two legs of the C-profile depending on a base 81, 81 ', on which a running surface 82, 82' for the rollers 74, in particular rollers such as step rollers, pallet rollers or

Chain rollers of a step belt or pallet belt run. In this case, the base 81 is arranged on the upper leg of the running rail 56A, 56B and the further base 81 'on the lower leg of the running rail 56A, 56B.

The pallet belt 58, whose rollers 74 are supported on the rails 56A, 56B, usually runs smoothly straight ahead. With increasing mileage, the

Chain joints, chain pins and the bearing bushes in the roller chains 65A, 65B worn and it can lead to different extensions between the left roller chain 65A and the right roller chain 65B. These minimal differences are sufficient that the arranged between the roller chains 65A, 65B pallets 64 are no longer arranged completely orthogonal to the direction of movement R and thereby a side run occurs. This lateral run or skew results in a lateral force F which causes the rollers 74 to deviate from their theoretical direction of movement R.

In this case, to guide the rollers 74 on the running rail 56A, 56B or on the corresponding running surfaces 82, 82 'are in the direction of movement R and thus in the longitudinal extent of the moving walk or the escalator, on the base 81, 81' spaced guide rails 90, 90 'arranged. The guide rails 90, 90 'have guide flanks 97 (see FIG. 5) which guide the rollers 74 of the pallet belt 58 on the rails 56A, 56B. The

Guide rails 90, 90 'take on the side force F on.

FIG. 4 is an enlarged view of a portion of that shown in FIG Roadway module 70 shown. One of the rails 56B with its upper base surface 81 can be seen. Fasteners 83 are formed on the base 81, with the aid of which a guide rail 90, which has corresponding fastening means 93, can be arranged on the base 81. The guide rail 90 thus limits laterally the running surface 82 of the rollers 74 (see FIG. 3) of a

Pallet band or step band.

As already mentioned, the running rail 56B is formed as a C-profile. For example, the track rail 56B can be made by a simple sheet bending process. The fastening means 83 of the running rail 56 B can be cut out before bending and stand after bending in the plane of the base 81 on the

Running rail 56B forth. The guide rails 90 are fastened by means of a screw-nut connection 100 on the base 81. Other types of connection are also conceivable, for example, by riveting, clinching, welding, soldering, gluing pinning and the like.

FIG. 5 shows the cross section of the running rail 56B with the base 81 in the sectional plane A-A shown in FIG. Also shown is a roller 74 of a pallet 64 of the pallet belt 58 (see FIG. 3) which rolls on the running surface 82 during driving operation. The guide strip 90 has a guide flank 97, which faces the roller 74. This guide flank 97 has a guide angle α, which is preferably 95 °. The guide rail 90 has as fastening means 93 a bore in which a bearing sleeve 94 is arranged. The bearing sleeve 94 has a collar, so that the guide rail 90 can be fastened without this resting on its entire underside on the base 81. This allows a simple, lateral deflection or a deflection without significant

Friction forces between the base 81 and its facing surface of the guide rail 90, transverse to the direction of movement R (see Figure 3) of the rollers 74 when acting on the guide rail 90, a side force F. The guide rail 90 is equipped with a sensor 95. This sensor 95 is on one of the leading edge 97

opposite side, arranged for example in the form of a strain gauge measuring bridge.

Due to the elongated extent of the guide rail 90, which is attached on both sides is, the sensor 95 is disposed between the two fastening means 93, so that a deflection or bending of the guide rail 90 can be detected in a force by the lateral force F. The guide rails 90 without sensor 95 are preferably fastened to the running rail 56B even without bearing sleeve 94, so that the mutually facing surfaces of the running rail 56B and the guide rails 90 abut each other and the guide rail 90 gives a higher rigidity transversely to the direction of movement of the rollers 74. Of course, the guide rail 90 may also have more than two attachment means 93, if none or as small as possible

Deflection of the Führungsleisten- center is required.

FIG. 6 shows a three-dimensional view of a guide strip 90. The elongated design of the guide strip 90 can also be clearly seen. In the end region 96, an entry angle β can be seen from its guide flank 97, which ensures that rollers 74 (see FIG Remove from the ideal line of the tread, captured again and guided along the guide edge 97 or passed. Also visible are two holes in the guide rail 90, which serve as fastening means 93 for fixing the guide rail 90 on a running rail 56A, 56B, for example, with a screw-nut connection 100, serve (see Figures 3 and 4).

On the side facing away from the guide edge 97, a sensor 95 is arranged in the form of a Dehnmessstreifen- measuring bridge. Of course, other sensors 95 can be used, which can detect a force acting on the guide rail 90 force or their elastic deformation or displacement relative to the running rail 56B. The measuring signal of the sensor 95 is sent via a measuring line 98 to a

Signal processing unit 99 transmitted or the measurement signal is through the

Signal processing unit 99 periodically retrieved at the sensor 95. The

Signal processing unit 99 processes the measurement signal and provides information representing the state of the escalator or the moving walk in the area of the sensor 95. From this information, actions such as a nonstop, a maintenance message, a calculation of the remaining life of the pallet band or step band and the like can be generated more. Furthermore, the information can be provided with a date and stored chronologically. The evaluation of the history thus created can be valuable information, for example, for structural Deliver adjustments.

FIGS. 7, 8 and 9 again essentially show the same section AA of FIG. 5. The only difference from FIG. 5 lies in the differently configured guide rails 190, 192, 193, for which reason the components identical in FIGS. 5, 7, 8 and 9 how the pallet 64, the track 82 and the sensor 95 have the same reference numerals. These are not described in detail.

FIG. 7 shows a second embodiment of a guide strip 190 with a sensor 95. A guide flank 191 of the guide strip 190 directed against the roller 74 has a first flank angle α> 90 ° and a second flank angle γ <90 °, so that one against the roller 74 directed, obtuse leading edge is present. This version is particularly suitable for measuring the condition of roller bandages. If the roller 74, which usually consists of a roller body and a bandage tire, begins to disintegrate due to wear, areas of the bandage tire can project unevenly around the circumference. These unequally protruding, rotating regions exert on the guide rail 190 a swelling force, whereby the sensor 95 detects a wave-shaped force curve. This force curve can be regarded as an indication of progressive destruction of the bandage tire of the roller 74.

The third embodiment of a guide rail 192 with a sensor 95 shown in FIG. 8 is particularly suitable for monitoring the bearing shells of rollers 74. The guide rail 192 has a guide flank for detecting a specific diameter range of the roller 74 in which its bearing (not shown) is arranged 194 whose flank angle δ <90 °. The guide flank 194 thus also has a directed against the roller 47 leading edge. Once a bearing shell of a roller 74 protrudes, it presses against this leading edge and exerts a force on the sensor 95.

FIG. 9 shows a fourth embodiment of a guide strip 193 with a first sensor 95 and with a second sensor 196. The first sensor 95 engages with each passing roller 174 by means of a feeler finger 195 in an annular release position 197 of the roller 174. In the normal state, each roller 174 thus generates a signal with two peaks. Now, when the diameter of the roller 174 becomes smaller due to wear, the annular clearance 197 decreases relative to the sensing finger 195, so that the hub of the roller 174 generates a third peak. But if by excessive

Dirt deposits between the track 82 and the roller 174, a resilient coating on the track 82 is formed, the roller 174 is lifted from the track 82, so that the sensing finger 195 can not immerse in the annular exemption 197. As a result, the feeler finger 195 during the passage of the roller 174 only on their bandage and the first sensor 95 detects only one more peak.

The second sensor 196 serves to detect structure-borne noise or vibrations on the pallet chain axis, which connects the pallet 64 to the roller 174.

Although the invention has been described in detail with reference to a lane module of a moving walkway, it is obvious that a lane module of an escalator can also be carried out in the same way. For example, several

Guide rails are used with differently shaped guide flanks and sensor arrangements. Furthermore, the track of the pallet band or step band leader can be formed in a first track and the track of the pallet band or step band retrace in a second track.
